What is Nickel 200?
Nickel 200 is commercially pure wrought nickel (UNS N02200, 2.4066, DIN N6) supplied to ASTM B160/B161/B162 as bar, sheet, plate, pipe and tube. Engineers specify it for resistance to caustic alkalis and for its combination of 70.2 W/m·K thermal conductivity, high formability (score 90) and easy welding (score 85), with 148 MPa yield and 47% elongation in the annealed temper. Strength is low, machining is gummy (score 35), and the carbon content can embrittle the metal above about 315 °C; low-carbon Nickel 201 is the direct alternative for hotter caustic service. Nickel 200 has a density of 8.89 g/cm³ (0.321 lb/in³), heavier than 88% of nickel alloy grades. It melts at 1,435°C (2,615 °F). Nickel 200 has a yield strength of 148 MPa (21.5 ksi) and a tensile strength of 462 MPa (67 ksi) — weaker than 98% of nickel alloy grades. Elongation at break is 47% and the elastic modulus is 204 GPa (29.6 Msi).

Working with Nickel 200
Is Nickel 200 easy to machine?
Gummy and work-hardening: use positive-rake sharp carbide, heavy positive feed, rigid setup, low-to-moderate speed (~25–45 m/min) and flood sulfur-chlorinated oil; never dwell in the cut.
Can Nickel 200 be welded?
Readily welded by GTAW/GMAW/SMAW with Ni-61 (ERNi-1) filler or ENi-1 electrodes; keep joints free of sulfur, lead and grease, use low heat input and stringer beads, no preheat or PWHT required.
Can Nickel 200 be formed, bent or molded?
Excellent cold formability — deep drawing, spinning and bending in the annealed temper; hot work 650–1230 °C, anneal 700–900 °C with rapid cooling.

Nickel 200 — frequently asked
What is Nickel 200 used for?
Nickel 200 is typically used for caustic soda evaporators and vessels, chlorination and dry-chlorine piping, electronic lead wires and terminals, food processing equipment, heat exchanger tubing and transducer diaphragms. In short: pure nickel chemical plate.
What is the yield strength of Nickel 200?
Nickel 200 has a typical yield strength of 148 MPa (21.5 ksi) and a tensile strength of 462 MPa (67 ksi) — weaker than 98% of nickel alloy grades. Strength varies by condition: see the 7 listed tempers.
Is Nickel 200 easy to machine?
Not especially — machinability is rated fair (35/100, better than 97% of nickel alloy grades). Gummy and work-hardening: use positive-rake sharp carbide, heavy positive feed, rigid setup, low-to-moderate speed (~25–45 m/min) and flood sulfur-chlorinated oil; never dwell in the cut.
Can Nickel 200 be welded?
Yes — weldability is rated excellent (85/100). Readily welded by GTAW/GMAW/SMAW with Ni-61 (ERNi-1) filler or ENi-1 electrodes; keep joints free of sulfur, lead and grease, use low heat input and stringer beads, no preheat or PWHT required.

What is the maximum service temperature of Nickel 200?
Nickel 200 is rated for continuous use to about 315°C (599 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

O is the default condition — standard stocked condition for plate, sheet, tube and forming blanks — maximum ductility and best corrosion behaviour. SPR: highest-strength wire condition for springs, woven mesh and fasteners in caustic or high-purity chemical service. Yield strength is 148 MPa in O versus 800 MPa in SPR.
